What is the meaning of the letter "g" or "a" after pressure measuring units? These letters indicate either the "manometric/ instrumental measuring mode" or the "absolute measuring mode", where the gauge-mode pressure (g from the English gauge) is one measured normally by observing the surrounding pressure and the absolute-mode pressure (a from the Engl. absolute) […]

In order to extract liquids from canisters, barrels it is helpful to use hand pumps with either bulb or piston, made from various materials depending on the corrosiveness of the liquid; we can tell you that a hand pump OTAL (Germany) with bulb, for an immersion depth of 90 cm, at a capacity of 26 […]

Why is DURAN glass so special? DURAN® is the world-wide standard for borosilicate glass 3.3 (DIN/ISO 3585). Its characteristics include maximum chemical resistance and high thermal resistance. The quality of the laboratory glassware of this trademark is given by the material (in other words by the glass and the glass type) but also by the […]

Even though the decree 466/79 regarding adhesive the regime of the toxic substances has been abrogated, it is useful to label the place where you keep such substances with warning labels for toxic and very toxic. In this respect we propose you self-adhesive labels with skull, explosion hazard, inflammable etc. Sizes: - 18x26 mm (one […]

We recommend you the fire blanket for laboratories; the asbestos fabrics are not fashionable anymore, asbestos is avoided due to health reasons; the blankets offered by us are made of glass fibre, are especially thermally insulated, nice at skin contact and non-toxic. They have two places in which they can be grabbed and quickly unfolded […]

NutriDisks are alternatives to the traditional Agar plates. The selective determinations and counting of the colonies are performed more easily with these NutriDisks. A cellulose disk is impregnated with a dehydrated base nutrient which, after being humidified with sterile distilled water becomes a proper nutritive medium for a micro-organism to be analysed. NutriDisks are delivered […]

About aerometers and densimeters with or without built-in thermometer: - the ones from inland have the classic range from 0,07 to 0,07 units. Example: for diesel fuel you need a densimeter or thermo-densimeter from 0,790 to 0,860 g/ml; - the ones from Germany have other ranges such as: 0,600 to 0,660 / 0,650 to 0,710 […]

You can check the freezing temperature of an antifreeze agent based on mono ethylene glycol more easily determining the index of refraction. Example: a mix of 50% MEG with 50% water has an index of refraction of 1,383 at 20 degrees C corresponding to -27 degrees freezing point.
